U.S.S. Mayflower NCC-1621

ST11 Timeline

The Starship Mayflower was part of a Starfleet task force destroyed by the Narada in the Battle of Vulcan on Stardate 2258.42. When the U.S.S. Enterprise NCC-1701 arrived on the scene, it nearly collided with the remains of the Mayflower‘s saucer section.^[1]

The special features on the DVD/BluRay release revealed that the ship pictured was the Mayflower. Additionally, although the novelization stated that the U.S.S. Enterprise NCC-1701 narrowly avoided colliding with the wreckage of the U.S.S. Defiant NCC-1764‘s saucer as it came out of warp, on-screen evidence shows that the saucer, in fact, belonged to the Mayflower, which was of the same class.^{[1, 2]}
